Abstract

The authors categorize some aspects of software process evolution and customization, and describe how they are handled in the EPOS PM system. Comparisons are made to other PM systems. A process model in EPOS consists of a schema of classes and meta-classes, and its model entities and relationships. There is an underlying software engineering database, EPOSDB, offering uniform versioning of all model parts and a context of nested cooperating transactions. Then, there is a reflective object-oriented process specification language, on top of the EPOSDB. Policies for model creation, composition, change, instantiation, refinement, and enaction are explicitly represented and are used by a set of PM automatic tools. The main tools are a planner to instantiate tasks, an execution manager to enact such tasks, and a PM manager to define, analyze, customize, and evolve the process schema.
